Electrophoretic deposition of nano-CoFe204 thick film
摘要
Abstract
Electrophoretic deposition was utilized for preparation of nano-CoFe2O4 thick film on Pt/Al203 substrates.The influence factors of electrophoretic deposition of nano-CoFe2O4 thick film were investigated. The Zeta potential value and conductivity of CoFe2O4 suspensions were measured to reflect suspension stability. The components and micromorphology of CoFe2O4 thick film were analyzed by X-ray diffraction and field emission scanning electron microscope.The ferromagnetic properties and leakage current of CoFe2O4 thick film measured by vibrating sample magnetometer and leakage current test instrument were also studied. The results show that electrophoretic deposition of CoFe2O4 thick film is feasible and the choice of deposition conditions is very important to the formation of good CoFe204 thick film. The coercive force and specific saturation magnetic moment of CoFe2O4 thick films are 225.1 kA/m and 31.17 A · m2/kg. The leakage current density is 3.0× 10-6 A/cm2.关键词
